I’ll bite as I know this tract as well or better than anyone I’ve ever met. In addition to mountain biking extensively on the land before it was built, I looked at every builders homes from day 1 and have all the original floorplans for all of them. I’ve followed the market there like a hawk for about 7 years.
4BR/2800 sq ft should be doable within the next 12 months at 750K and it might even be a decent lot/location. 12 months after that 700K should be doable. Prices may hit 650K at a bottom but that is iffy and probably for a house you wouldnt necessarily want to buy. Just my opinion which is worth as much as you just paid for it…
